如果标题令人困惑，我很抱歉。因此，我正在实现一个聊天应用程序，其中有一个ChatRow列表，点击后，将进入MessageView。当用户发送消息时，ChatRow列表可能会重新排序，因为我对它们排序的方式是，包含最新消息的消息放在顶部。
代码大致如下所示（如果需要更多细节，请告诉我）：

struct ContentView: View {
    @EnvironmentObject var chatsManager: ChatsManager
    @EnvironmentObject var messagesManager: MessagesManager

     var body: some View {
         NavigationView{
             VStack{
                 // Some Views
                 VStack{
                     if chatsManager.chats.isEmpty{
                      Text("you have no chats for now").frame(maxHeight:.infinity, alignment: .top)
                     }
                     else {
                         List() {
                             ForEach($chatsManager.chats, id: \.id){ $chat in
                                 NavigationLink (destination:
                                           MessageView(chat: chat)
                                           .onAppear{messagesManager.fetchMessages(from: chat.id)}
                                 ){ ChatRow(chat: $chat) }
                             }
                     }.listStyle(.plain)
                 }
             }
         }.navigationBarTitle("").navigationBarHidden(true)
             
        }.navigationViewStyle(.stack)
            
     }
}

一个非常奇怪的事情是，如果我在List滚动到顶部时点击视口中的聊天，一切都会完美地工作（没有自动弹出，当手动弹出时List会正确更新）。
但是，如果我向下滚动列表时，顶部的几个ChatRow得到滚动离开屏幕，我会弹出回来，如果我发送任何消息。
我在网上搜索发现List延迟加载元素，所以这可能是问题的原因，但是我找不到解决的方法。

重现问题的代码

只需将以下代码复制到一个文件中并运行。
观察当您点击进入第一个聊天并点击按钮与点击进入最后一个聊天并点击按钮时，事情的行为是如何不同的。

import Combine

                 VStack{
                         List() {
